Hm, this actually sounds about right to me, or at least closer to right. The 'crew' bookmark[0] has felt like a band-aid - it doesn't really solve the problem of "knowing where changes came from" in an automatic way, as each source has to cooperate and add their own bookmark. Using the divergence markers on the @ bookmark might be the right thing. Perhaps this implies a mode where 'hg pull' never advances the local bookmark? That is, when mpm would pull, he'd get a @@local and a @@crew, and then could see where @@local was even if it was an ancestor of @@crew. I know that's not quite what we'd originally thought, but it seems to me that might solve mpm's "where did things come from?" problems.
